To all 'wlwmit may concern:

Be it known that we, JOHN Q. SHERMAN and AooLrH F. EUonnNHoFnR, citizens of the United States, and residents of the city of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Manifold ing Attachments for Type-\Vriters, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, forming part of this specificatio Our invention relates to-manifolding attachments for typewriters. In devices of this nature, the customary .practice in the past has been to provide means traveling with the typewriter carriage for supplying a number of strips of paper. These stri s of paper have then been brought around t e platen of the typewriter and the duplicate copies made by means of a number of strips of printing ribbon wound in some desired way so as to pass a number of times in front of the printing point on the platen. There is considerable difliculty in these structures in feeding the paper, and it is quite difficult to keep the paper in proper alinement.

It is the object of this invention to do away with the ribbon method of manifolding and to positively feed around the printing platen on the typewriter the manifolding sheets. It is a further object to provide for perfect alinement of the strips of paper by means of toothed feeding wheels which engage in perforations in the paper.

It is also an'object to provide a carriage for the rolls of manifolding paper which moves easily with the typewriterv carriage, and it is further an object to provide means for using carbon paper in connection with the manifolding paper instead of ribbon.

These objects and other advantages which will be noted we accomplish by that certain construction and arrangement of parts to be hereinafter specifically pointed out and claimed. y

In the drawings,

Fig. 2 is a rear elevation of the carriage for the manifolding paper.

Fig. 3 is a detail front elevation of the,

toothed feeding wheel at the left side of the typewriter.

Fig 4 is a side elevation of said parts shown in Fig. 3. a

Fig. 5 is a top plan view of the stripper.

Fig. 6 is a detail front elevation showing the operative connection between the platen and the feed shaft for the feeding disks.

To the frame 1 of the typewriter is suitably secured the base 2 for the carriage of the manifolding devices. Mounted on .this base, which is thicker at the right hand end so as to present an inclined surface from left to right, are the rails 3. The carriage travels on these rails, and has a bottom 4 and frame pieces 5, 5. These frame pieces are divided into two side arms 6, 6, at the sides, and extendupwardly from these arms ,to form bearings for rollers 8 and 9, and extend forwardly at 10 to mount the carbon paper and various idler rollers as will be hereafter noted. The arms 6, 6 are slotted at 11, 11, for inserting the splndles 12,

12, of two lower rolls of manifolding paper.

treme upper edge of the forward extension 10 of the side frame pieces. The uppermost of the two rear paper rolls has its film B carried over the idler roller 9, brought forwardly and over the idler roller 16 mounted between the extensions 10. The forward. of the two lower rolls has its film C of pa-,

per brought up over the idler roller 17 across the frame pieces and this film is brought forward and over an idler 18 extending between the portions 10 of the frame.

Mounted between the idlers 15 and 16 is a roll of carbon paper A. Between the rolls 16'and 18 is a rollofcarbon paper B, and mounted beneath the idler 18 is a third roll of carbon paper 0. These rolls of carbon paper have spindles 19, which extend into bosses 20 at the left hand of the extension 10, and which extend into plungers 21, mounted .in the other side of the frame. These plungers have disks 22 mounted around their inner ends and springs 23 maintain these disks frictionally against the carbon paper rolls. The plungers have heads 24 by which this spring tension may be relieved for unrolling a portion of carbon paper. The films of paper are brought down and around the platen 25 of the typewriter in the customary manner for typewriter paper. The film D from the forward upper roll of paper passes direct to the printing platen from the carriage.

In insertinv the paper around the platen, the film D is drawn out and the carbon paper 0 pulled out and after that on top of the carbon paper the film C is drawn forward and so on, sothat between each of the four sheets is a piece of carbon paper. This paper is then inserted around the platen in the ordinarymanner, suflicient being drawn out so that the edges of the paper will extend up through the. feeding devices to be hereinafter described, and so that the carbon paper will extend up to the printing point on the platen.

For moving the carriage for the manifolding paper, bars 26, 26, are connected to the carriage of the typewriter and pivotally connected to the manifolding carriage at 27, So that when the carriage moves the manifolding carriage will move .also. In view of the fact that the manifolding carriage is on an inclined track, the springs in the typewriter carriage will not have to take care of the work in moving the carriage for the manifolding paper, which is a considerable advantage, as in the past it has been found that the typewriter springs are worn excessively and often fail to properly move the typewriter carriage together with the heavy manifolding carriage. I

The mechanism for feeding the films of aper by the platen will now described. lates 28 are provided, one for each end of v the machine, and these plates have a clamp member diagrammatically shown at 29, whereby they are mounted on the cross rod 30, which in this make of typewriter carries the paper clamping fingers. The plate has a rearward extension 31. which extends at an angle so as to be bolted to the sides of the, carriage. The plate extends forwardly at 32, and provides journals 33 for a cross shaft 34. This shaft has a keyway'35 in it, and on the shaft are a pair of wheels 01- disks 36, having teeth 37. These disks have their hubs keyed so that they will slide along the shaft 34 to any desired position, and a plate 38 having cutaway portions 39 therein is mounted on the rod 30, these cutaway portions being adapted to receive the teeth.

The member 38 is preferably under spring pressure, and its forward end, inwhich the slots 39 are located, is bent downwardly at '40 so as to lie adjacent to the disks 36. The

.' paper films are brought up around the platen and are provided with a series of perforations spaced apart the distance of the with a pinion 42 on the shaft 43 of theplaten of the machine. Thus the usual typewriter mechanism for turning the platen can be used to revolve the shaft 34 and with it the disks 36.

The carbon paper will not be wide enough to be engaged by the teeth on the disks, and it is not intended to have the carbon paper fed to the machine with the films of manifold paper. Only enough carbon paper is to be drawn ofi the rolls to extend beyond the printing point on the platen, and the friction on the rolls of carbon paper will prevent its being drawn through with the manifolding paper. It is preferred to disengage altogether the usual friction mechanism against the platen of the typewriter, so that the films of manifolding paper are actuated solely by the two disks heretofore mentioned.

When a portion of the carbon paper is worn out, the operator may, by releasing the tension on the rolls of carbon paper, 71. e. by pulling out the plunger 24 (Fig. 2), allow the carbon paper to travel onward slightly with the manifolding paper. The releasing of the plunger 24 will again hold tbecarbon paper, sothat the newly exposed portion thereof will be used until the next change is made.

By providing paper with its edges perforated at regulated intervals in connection with the toothed sprockets or disks, it can be seen that an absolute alinement for manifolding paper is always maintained. On this manifolding device, therefore, rolls consisting of blank forms of various kinds can be filled in,'it being only necessary to get the proper lines on the four films in register at the beginning of an operation, whereupon they will remain in com lete registry until the paper is torn off. r the purpose of tearing off the paper, a knife 44 is mounted on a plate 44*,hinged at 44 on the top of an extension 45 of the member 28 which provides the disk shaft. This plate 44 extends down at 44 so as to form a coacting, opposed stripper plate in connection with the member 38. It is to be cut away similarly to the member 38.
